Join us to discover more interesting things about the stars! The fastest stars in the Milky Way is moving at a speed of 1,200 km / s, can escape from the Milky Way in about 25 million years.
According to the expert group of the European Southern Observatory (ESO), 708 US star is moving at a speed of 1,200 km / s, or 4.3 million km / h.
"At this rate, you can travel from the Earth to the Moon in just 5 minutes", RT 8/3 day quoting astronomer EugeneMagnier at the University of Hawaii, said.
According to Space, US 708 is considered the fastest stars in the Milky Way that astronomers ever discovered. Speed will allow it to escape the gravitational pull of the galaxy and out into the space between the galaxies. The star was first discovered in 2005.
Generally, the faster the star has similarities to the Sun and slower US 708. They are to be used to have a pair. When a star is sucked into supermassive black holes in the center of the Milky Way, the rest will be freed from the entire galaxy.
However, the astronomers believe that the US 708 has a close relationship with another star, even closer to the black hole also inseparable from them. Under current assumptions, before moving through the galaxy, US 708 used to be a cool giant star, but a star was orbiting it sucks losing most of hydrogen. Scientists suspect this companion star that exploded.
The astronomers believe that the stars move at speeds of up to 3.2 million km / h in the Milky Way black hole had nearly been swallowed.
astronomers discovered 6 supernovae speed very fast flying near the black hole at the center of the Milky Way, where the density dust that the light of the star largely impenetrable, Space reports.
"They are extremely fast-moving objects and not subject to the gravity any other object in the galaxy. We have a similar mass of the sun", Keith Hawkins, a student astronomy at Ohio University USA, stated.
This is the first time astronomers discovered the star super speed. Although moving in the center of the Milky Way, they are not obscured by dust so people can see them with telescopes.
Some astronomers predict that the rate supernovae remnants of a binary star system. After the supermassive black hole at the center of a galaxy swallowed one of the two stars, it pushes the remaining stars into space with tremendous speed.
